Abstract
The high strength of thin metallic and inorganic fibers, whiskers, and flakes can be exploited if they are properly protected and bonded together by a suitable adhesive or matrix material. The principles which appear to influence the strength of thin specimens and their mechanical behavior in such a matrix are reviewed. Qualitative attention is given to series and parallel failure mechanisms in the fibers, to the description of brittle behavior, to bonding and the mechanisms of stress transfer, and to testing methods and evaluations. Semi-quantitative relations are adduced to suggest optimization of mechanical properties, and composites containing SiC are discussed to illustrate these relations. On the basis of the principles discussed, suggestions are made for selecting future composite materials and designing them for specific applications.
